Just want to make IBMers aware, if you transfer to a job at Red Hat you will likely have to formally exit IBM and become a new Red Hat employee.
If you are under age 55, this can mean losing any IBM seniority, future health care account funds and other benefits you may have accumulated over time. At the same time, your IBM 401K (and any pension account you may have) will become locked to age 59.5, because you are exiting IBM and going to be work for a wholly owned subsidiary.
That means starting over with a new 401K and building it up from scratch before you can take loans. I am not advocating for any direction here, each person has their own path to carve out...
But do want to make sure that people are informed and ask all right the questions that may impact your health and retirement, if you find yourself with this option.
